I have a datatable which i get from the databasemanager class, and i would need to transform that data into a hierarchical structure
either binding it directly to a .net treeview control or in memory first .
i have an ID column, and a ParentID column.what i do not know necessarily is the parent ID to start with. so first thing to do would be to find out which node is the parent ID.
what would be best practice to loop over this table and make it hierarchical
BranchId ParentId ProductCount HasBranchChildren Name
0 NULL 48 1 Categories
1 0 20 1 CategoryA
2 1 10 1 CategoryA1
3 1 8 0 CategoryA2
4 1 2 0 CategoryA3
5 2 4 0 CategoryA1.1
6 2 6 0 CategoryA1.2
7 0 28 1 CategoryB
8 7 20 0 CategoryB1
9 7 8 0 CategoryB2
this would be an example datatable of course it will have hundreds of items, and it does not always start at the root node, its possible that with a request a certain subset of categories is requested, however i've talked with the database team and they will give me NULL on root nodes in the above example that would be element 0 in the table ....

When a user updates a record via detailsview in table 1 (TA), I need to display child records which are in table 2 (SG) and their child records which are in table 3 (SC). I tried to use DataList inside another DataList but I cannot filter the table 3 records based on returned values of table 2. I am also using TableAdapters and added a relation for table 3 to table 2 via both primary keys of table 2. I selected to create Both Relation and Foreign Key Constraint and Cascade as Accep/Reject Rule.
For my select statement on table 2, I filter it via WHERE (SGPrimaryKeyCd = :SGPrimaryKeyCd) AND (SGPrimaryKeyDate = :SGPrimaryKeyDate) and return the correct records based on values entered by the user.
For my select statement on table 3, I tried using a WHERE clause but didn't work. Without a Where clause I get all the records, of course. I thought relation would take care of filtering.

This maybe simple thign to you but I need to display data in below hierarchical format. I am using ASP.NET, VB.NET.
Company
- Product1

There will be only 1 root node (Company) in my case. And it will have 1 or more child nodes. These child nodes will not have any further child, ie they are leaf nodes.
How to display this data in this format using ASP.NET & VB.NET?

I want to know what the easiest way is to copy one database structure to another blank database. I want tables, stored procedures and functions copied over but none of the data within the tables. I can export it...but then all the data also gets carried over, which I don't know. What would be the best way to carry this out?

I have a requirement where I would not know the columns and any result set information at design-time, so I'd be generating the data-display control dynamically.What is the most suitable way to display this type of information on-the-fly in a table/grid like structure on an ASP.NET page considering the following parameters (in order of importance):
Performance
Extensibility
Usability
I know I can dynamically generate a gridview/repeater/listview control but what I'd like to understand is which option (from stated ones or any other beyond these) would be an optimal solution..S. Paging and Sorting are part of desired functionalities, but can be overlooked if the solution is overwhelming. :)

I've managed to render TreeView using custom made Hierarchical Datasource based on Linq queries on self referencing table. Rendered output looks well but... Every Node in NodeCollection has the same index = 0. Therefore when I click on any collapse button - the whole tree Collapses. In generated html every node has the same id = MainContent_TreeView1n0 I suppose n0 should increment to n1 n2 n3 and so on.

So here is the situation - there is data on master records - its a hierarhical view - something like (ID, IDParent, Title) and detail data - (ID, IDMaster, Details)
And like to build UI using an TreeView - binded with master data - and an GridView - binded with detail data.
Question is witch property to use to create the master/detail chain between Datasources - oh, I've forgot to tell I'm using an ObjectDataSource?

I'm in the process of developing a survey system. The tables / fields that are related to my question are:
[Code]....
My issues with this way were:
1) The Data Adaptors receive ALL the records from their correspondent tables. Not a good practice, I believe.
2) If, at some point, the survey had no categories, questions or choices under its child records, an error occurs when the page tries to build the Data Relation. With the work flow I had in mind for the system, this is bound to happen becuase all the Data entry pages (Add Category, Add Question, Add Choice) will be displaying the newly-created survey in a similar fashion (at which point, the survey will have no child records and so an error would occur)

I have a gridview that displays in the following manner. What I am trying to accomplish to is if you see the columns with the heading(s) Name, LegName, MedicalConditions, DateofBirth and id displays as two rows, as it normally would, but what I would like to do is to have all that data display in ONE Row because it all belongs to one registration. If you look at the two images, image one is how the data comes out of the DB normally. Image two is how I would like to be. keep in mind that this is a small example and I actually have more fields than just this, so I am looking for something extensible. Anyone have any thoughts on how I could modify the gridview to display my data like this?

I have developed an application using Visual Studio 2008. I have a hirerchical gridview and on every row i have a "Payment" button which actually inserts a payment entry in database. Here is the sample screen of that gridview so u have an idea what i am doing. Problem is that whenever user pressed the button of "PAYMENT" it is inserting multiple records in database..it should only fire once and i am failed to understand why its firing multiple times. Refer this link for my payment screen: [URL]
